Hi Liv74766
Thanks for your question!
Magnets do work under water! Magnets work because they create an electromagnetic field around them. Those attraction/repulsion forces has not problem passing through water as water is not magnetic.
Well, yes they do. Because, the waves they pass (magnetic waves), can easily pass when these are in water. There is no effect of water on these waves. Their strength to attract and repel iron will still be the same as out side the water. Hey, why don’t you do this experiment today? And let me know as well 🙂
Hi Liv! Interesting question. I’ve never tried it myself but as the other guys have said, they will still work.
However, they will not necessarily work in the same way. Under water there are other forces also competing, such as buoyancy (which makes some things float) and increased resistance (it’s harder to move your hand through water than through air). So while they will work, the magnets will need to be more powerful to perform the same job. You could test this by trying to attract iron filings to a magnet on a regular table, and comparing it to how they are attracted in a water tank.

I put a magnet underwater today and it worked. I tried it with a magnet, a fridge magnet and a fish tank magnet and they all worked!

That’s awesome Liv! Nice work 🙂
What are you going to do for your next experiment then?
